Things I liked:Beautiful weapon, functional accessory rails, will fire 30 rounds faster than I am capable of squeezing them off. "You'll go through a tin of pellets in one sitting" is a bit of an understatement. It is incredibly fun to shoot and not so loud that you'll wake the neighbors. It's actually heavier than the 9mm version and kicks more than you'd expect on a full cartridge. Things I would have changed:Internal screw posts kind of weak. The gun starts to open up a little bit after 500 rounds with slight gaps in the handle and you can start to feel the C02 blowby. This can be fixed easily by the company, but you can reinforce your own too. The magazine is a bit tedious to load and as of now there aren't spares available. The metal post sights are REALLY bad. Mine were impossible to zero.What others should know:If you want to shoot anything past 10 yards, get some sort of optics. I skimped on the Walther PS22 that comes in the kit version (also available at pyramid air) and within two weeks bought it separately. There's a 4x scope made for it that I can't seem to find anywhere (?). With the PS22, I really have few complaints about this carbine. Tight groups at 25 yards.
